lshw 显示cpu 4 disable ，请问这颗cpu指的是哪颗，是NPU吗？

 *-cpu:4 DISABLED
      description: CPU
      product: idle-states
      physical id: 5
      bus info: cpu@4

在demesg中显示 NPU不能 request resgion for resource

运行npu demo 返回E RKNN: [16:39:54.041] failed to submit!, op id: 1
小白请问一下这三者之间有关联吗？

我今天也遇到了这个问题，wiki提供的rknn example已经不能用了，我用rockchip最新的1.2版本编译后可以使用

1，安装编译所需依赖
sudo apt install git cmake build-essential

2，下载rockchip最新的rknpu2代码
git clone https://github.com/rockchip-linux/rknpu2

3，进入代码目录，创建build目录
cd rknpu2/examples/rknn_ssd_demo
mkdir build && cd build

4，修改CMakeLists.txt，防止编译出错
vim …/CMakeLists.txt
将23行的armhf改为aarch64

5，编译
cmake -DCMAKE_SYSTEM_NAME=Linux -DTARGET_SOC=rk356x …
make -j3

6，将model目录复制到build目录
cp -r …/model/ .

7，运行
./rknn_ssd_demo ./model/RK356X/ssd_inception_v2.rknn ./model/road.bmp
可以得到如下输出：

谢谢啊 写的非常详细 我也找时间试一下 npu demo test应该是在官方的ubuntu debian上都可以跑的吧 好像从卖家还是哪里我记不清楚了 说是debian比较好支持，我debian不太熟 上午琢磨着是不是刷个ubuntu 呢

Thanks, following your guide ,it is finally working in my Rock 3A, Thanks
